The forum rules are simple. Only post within the forums and topics specific to your subject. Please do not spam as it will be removed.
Also if you are going to add links within a post or reply make sure it is worthwhile and relevant to the topic you are in or the link will be removed.
NOTE: You can place any link you want within your signature, so it stays within every post or replies you make within the forum. To edit your forum signature log into your account and go to My Profile > Edit Profile.
